Abstract

The project is mainly determined on the activity based measurement of the blood flow in humans. The objective of the project is to measure the blood flow in human limbs and to study the blood flow characteristics using an innovative methodology called Impedance plethysmography. It is also called as impedance test or blood flow or impedance phlebography. It can be used to measure arterial volume change that occurs with propagation of the blood pressure pulse in a limb segment. For this measurement, we assume a constant value of blood resistivity. However, blood resistivity may change under both physiological and pathological conditions. It is a non-invasive test that uses electrical monitoring in the form of resistance (impedance) changes to measure blood flow in veins of the leg. Information from this test helps doctors detect deep vein thrombosis. Using conductive jelly, the examiner strategically places four electrodes on the patient’s calf. These electrodes are used to measure the impedance of the body and it is amplified. It is used to detect blood clots lodged in the deep veins of the leg, Screen patients who are likely to have blood clots in the leg, Detect the source of blood clots in the lungs (pulmonary emboli). It measures the blood volume changes in the human physiology which is used to detect the cardiovascular problems in the human.
